RegistrationType and RegistrationId attributes of <CustomAction> element are being used in the declarative SharePoint 2010 user interface customizations when they target any list/library related Ribbon UI.
RegistrationType and RegistrationId attributes works in pair only. They
form a combination where RegistrationType is a type of criterion for
applying customization and RegistrationId is a value of this criterion
to compare with content.
